No. The 864 HC is a NEMA Type 1 enclosure, which is an indoor-only rating meant to keep personnel away from live parts and keep out falling dirt. It gives no protection against rain, hose-down, dust or oil, so for an exterior wall, a parking structure or a wet process area you need a Type 3R, 4 or 4X box instead. Indoor electrical rooms, mechanical spaces, back-of-house corridors and dry ceiling plenums are where this one belongs.

Hinged, which is the practical difference between the HC enclosure and a standard screw cover box. The door swings on the box so you are not holding a loose cover or chasing screws on a ladder, and it uses a recessed pull ring with a friction dimple to hold shut. The cover is also removable if you need it fully out of the way while pulling wire.

The 864 HC measures 8 inches high, 6 inches wide and 4 inches deep, and it weighs 3.9 lb. That 4 inch depth is the number to check first if you are stacking terminal blocks or turning large conductors inside, since bending space, not the face size, is usually what runs out on a box this small.

Knockouts are already provided. The 864 HC has 3 bottom knockouts and 4 knockouts in the sides, plus knockouts on the top, so conduit can enter from more than one direction without a hole saw or a Greenlee punch. If your raceway sizes do not match the factory knockouts, you can still punch the 16 gauge carbon steel body, but plan the entries before you mount it.

It is a surface mount enclosure with thru holes in the back for fastening straight to a wall, strut or plywood backboard. Fasteners are chosen to suit the substrate and are not part of the box, so order your anchors or strut hardware with it. Nothing about the box requires a mounting bracket.

It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the United States. That UL 50 reference and the Type 1 rating are what an inspector or a spec reviewer will be looking for on an indoor junction box.

Order Eaton B-Line 864 HC. The number follows the size, 8 high by 6 wide by 4 deep, with HC meaning the hinged cover version. If someone on the job specified an 864 without the HC suffix, that is the screw cover variant, not this one.

The 864 HC is painted ANSI 61 gray, the standard gray used across most commercial and industrial enclosure lines, so it will read as a match next to existing panels and pull boxes in the same finish. It is carbon steel rather than stainless or fiberglass, so touch-up paint handles field scratches.
